Mr. Brown is a young and (success) businessman. He (live) in the countryside and he often drives his car to his office.
One day, while Mr. Brown (drive) down a street the loud music on, he saw some children running around. Suddenly, a stone (fly) to his car's door! He jumped of the car and shouted to a girl, "That's my new car and it will (cost) a lot of money to repair it!"
"I'm sorry...I didn't know what else (do)." The girl said.
With tears in her eyes, the girl pointed to a boy lying on the ground. "It's my brother." She said. "He fell out of his wheelchair and I (not lift) him up. He's too heavy for me. I just wanted to get your attention." After (hear) her words, Mr. Brown lifted the boy back into the wheelchair.
Mr. Brown keeps the dent (凹痕) to remind him not to go through life so fast, or someone will have to throw a stone at you to get your attention!
